offset and limit are used for pagination; in MySQL this
relates directly to the LIMIT clause. If you use offset or limit, then your SQL must not
contain a LIMIT clause. prefix is the string that is replaced in the SQL by the database
table prefix; it would be unusual to change this from the default #__.
Parameters sql Query
[offset] Start record
[limit] Maximum number of records
[prefix] Table prefix to substitue
static test( ) : boolean
Determines if the driver (subclass) is compatible with the current environment.
Returns true of the driver is compatible with the current environment
updateObject( table : string, &object : object, keyName : string,
updateNulls : boolean=true ) : boolean

record. If updateNulls is true, object properties that are null will still be used to update
the record in the table.
Parameters table Table name
object Record object
keyName Primary key
[updateNulls] Update values even if they are null
